From the moment he awakened in the body of the young man everyone called Rein, not once had he opened his eyes to find himself returned to the world he once knew. Each time consciousness claimed him, his gaze met the same vaulted ceiling carved with softly glowing arcane glyphs, the air tinged with the scent of herbs and magical ink.
The longer he remained here, the clearer the truth became: this body no longer felt borrowed. It felt… his.
Reluctant as he was to admit it, he had begun to accept—carefully, with reservations—that he might be trapped in this form indefinitely.
As a scientist, he had been trained to confront reality no matter how improbable. Hypotheses came first; denial came last.
“The survival rate from that explosion was under ten percent,” he murmured one morning, lying with his hands folded behind his head, eyes fixed on the overhead vent.
“The odds say my former life ended there. And if I factor in time dilation… who knows how long it’s been since that moment? Brooding over it is pointless. What matters now is adaptation.”
A faint whistle slipped through the metal slats as cool air seeped in, like wind humming a forgotten lullaby.
He had begun estimating time by the glow cycle of the glyphs overhead. They burned as bright as daylight for roughly twelve hours, then dimmed to a softer radiance for the remaining twelve.
That alone suggested a familiar rhythm.
The day–night cycle here appeared to span approximately twenty-four hours. More importantly, he suffered no signs of temporal disorientation. His sleeping patterns, appetite, even the sense of fatigue in his muscles all aligned disturbingly well with what he remembered from Earth.
“A full day is roughly twenty-four hours,” he concluded quietly.
“If this is a planet, then its size or rotational speed must be similar to Earth’s. Gravity, atmospheric pressure—even the oxygen–nitrogen balance—everything feels familiar.”
And that, more than anything else, unsettled him.
The probability of a near-identical twin planet—a mirror world—was astronomically low under any single-universe model.
Unless… it wasn’t a single universe.
A parallel reality. A multiverse.
He exhaled slowly, pushing the thought aside. For now, it was all conjecture. There were no windows in this room, and he still hadn’t been permitted to step outside even once.
From casual conversations with a girl named Ingrid—framed as attempts to jog his memory—he had learned that the building housing him served as a research and treatment wing under the Department of Healing of the Arcadia Academy of Magic. The entire place fell under the direct supervision of Master Chloe, reputed to be one of the most powerful healers in Arcadia.
Chloe’s reputation bordered on myth. As long as a patient still drew breath, her healing magic could restore them in an instant. Around the Academy, people spoke of her less as an instructor and more as a saint.
Especially Ingrid. Her admiration hovered somewhere between respect and outright reverence.
Rhys found it quietly amusing. The girl’s expression was no different from a devoted fan gushing over her favorite idol—apparently, some behaviors transcended worlds.
The room itself was no ordinary patient ward. It was a special chamber reserved for experimental treatment and critical cases under Chloe’s direct care. Three sturdy wooden beds lined one wall, each veiled in sheer white curtains. Another wall was packed with glass cabinets holding color-coded vials, crushed herbs, enchanted elixirs, ancient metallic containers, and softly glowing mana crystals.
At the center stood an enormous desk cluttered with towering stacks of grimoires, scrolls inked with arcane formulas, quill pens, crystal globes, and gently flickering lamps. The space balanced delicately between laboratory and private library.
Access was strictly controlled. As far as Rhys knew, only Chloe and Ingrid—her personal aide—were authorized to enter. He hadn’t seen anyone else.
Ingrid had mentioned on the second day after his awakening that the chamber was completely off-limits to ordinary students. It housed not only confidential medical instruments, but Chloe’s private research materials as well.
So for nearly two weeks, Rhys had been “vacationing” here.
Each morning, he woke, stared at the vaulted ceiling, and waited for the “real world” to resume.
It never did.
The glowing symbols carved into the stone merely hummed back at him—like neon signs advertising a magical club he had never asked to join.
“Well, Rhys,” he muttered one afternoon, hands still folded behind his head as he watched the vent.
“If this is a dream, it’s a remarkably high-budget one. Gravity feels like a steady 9.8 meters per second squared. No temporal nausea. My knees don’t even creak.”
He let out a short breath.
“Either I’m on a parallel Earth… or the universe decided to copy-paste the fundamental constants just to keep things familiar.”
It was the kind of puzzle Richard Feynman would have loved—a world that looked like a fantasy novel, but behaved like a physics lab.
The most peculiar part, however, was language.
When Ingrid spoke, he didn’t hear English—yet he understood her perfectly. It felt as though his brain was running a high-speed translation layer, interpreting intent and meaning faster than conscious thought.
He glanced up at a jagged glyph etched into the ceiling. For a moment, it was nothing but tangled lines.
Then it clicked.
“Ah. A thermostat,” Rhys smirked. “So the glowing paint’s actually a thermal regulator. Over-engineered for a bedroom… but I’m not complaining.”
It felt like inheriting a secondhand computer with the previous owner’s files still intact. The hardware was Rein’s.
The interface was all Rhys.
The strangest part, though, was his internal sense of measurement.
He looked at the heavy wooden desk in the center of the room. Ingrid had called it “five feet long.” To him, that felt hopelessly vague.
Without effort, his mind snapped to a precise value.
1.52 meters.
There was no calculation—just recognition. A vial of blue elixir wasn’t “half a cup,” but 118 milliliters. A stone slab wasn’t “three inches thick,” but 7.62 centimeters.
“My internal processor is apparently stuck on SI units,” he mused, reaching for a leather-bound book.
“Even in another world, my brain refuses to think in inches. Good. Precision is the only thing keeping me sane right now.”
He flipped through The Chronicles of Aetheria, eyes darting across the yellowed pages. At first, he’d sounded out the words like a child learning to read. Within hours, the pace accelerated.
The information wasn’t being learned.
It was being unlocked.
“Whoever Rein was,” Rhys thought, closing the tome on geopolitics, “he was a voracious reader.”
He leaned back, a dry, satisfied grin touching his lips.
“At least,” he murmured,
“I brought the best calculator in two worlds.”
But the grin faded as he realized just how effortless that “calculation” had been. It wasn’t merely a mental trick; it felt natural—habitual, even. The longer he stayed here, the more the jagged edges of this alien world seemed to smooth out, as if he were being quietly absorbed into the rhythm of Arath itself.
“Remarkable,” he mused, tapping his temple.
“I’m not just a passenger in this body. I’m tapping into its pre-existing neural pathways.”
It was a fascinating—if faintly unsettling—hypothesis. The instincts and deep-seated memories embedded in Rein’s biology were still intact, running silently in the background. At times, Rhys felt like he was using someone else’s computer: a high-end workstation already configured with all the essential software.
He didn’t need to learn how to live here.
He only needed to figure out which “keys” to press.
“Convenient,” he admitted with a quiet, weary sigh.
“Without these built-in functions, surviving here wouldn’t just be difficult—it’d be a statistical impossibility.”
Over the following weeks, with no windows and no visitors beyond Ingrid, Rhys did the only thing that felt natural. He turned the chamber into a private archive.
If he was going to be an uninvited guest in this universe, he needed to know who owned the land—and who was currently trying to tear it apart.
With a reluctant grunt, he hauled the massive tome The Chronicles of Aetheria toward him. The heavy leather cover thudded against the wooden table. He pried it open once more, letting ink-stained maps and forgotten borders bleed back into his mind.
The text laid out the fundamentals.
This world was called Arath—a vast planetary system divided into five major continents.
Aetheria, the so-called Central Continent, sat at its heart, regarded by local scholars as the axis around which the others revolved. Beyond it lay the periphery: Galathor to the frozen north, Avonia to the west, Arvandor in the south, and storm-shrouded Elderia to the east.
Rhys skimmed the summaries of these outer lands. The sheer volume of information gave him pause. A full analysis of global geography would take months—time he wasn’t prepared to spend yet.
He needed the neighborhood first.
Brushing dust from a tome dedicated solely to Aetheria, he opened it—and immediately felt his initial hunch confirmed.
Royal Road is the home of this novel. Visit there to read the original and support the author.
The continent wasn’t merely a patchwork of kingdoms.
It was a divided house.
Eight kingdoms and one religious dominion shared the land, yet the balance was dictated by two undisputed superpowers: the Kingdom of Arcadia and the Calandria Empire.
The book laid the board out with clinical precision.
Arcadia held the east. Calandria claimed the west.
They were divided not just by ideology, but by geography—a brutal scar of terrain formed by the Arnak Mountains and the lightless canopy of the Koona Forest. These weren’t just landmarks; they were a natural demilitarized zone in a world perpetually on the brink.
“It’s a classic divide,” Rhys thought, tracing the border with a fingertip.
“One side hoards knowledge. The other builds the better hammer. And the mountains in between are the only reason they haven’t flattened each other yet.”
He flipped the page, his mind automatically restructuring the information into a mental spreadsheet.
Aramel Freeport came first.
To the average historian, it was a cultural melting pot. To Rhys, it was a logistical masterpiece. Situated on the southern coast, it functioned as Aetheria’s primary neural limb for commerce.
The largest seaport on the continent.
His eyes scanned sketches of crowded docks and multi-ethnic districts.
High diversity means high chaos… but also high information flow.
If I ever need to disappear—or find something that shouldn’t exist—this is the node.
His gaze drifted southeast, settling on a vast yellow void.
The Zeppelin Desert Kingdom.
Not merely a wasteland, but a fortress of extreme variables. The Saharadus Desert dominated the region, stretching to the coast like a scorched barrier. Survival here depended on mastery of wind and sand magic—kinetic energy repurposed into infrastructure.
They traded in high-value assets: rare herbs, artifacts, relics pulled from the heat.
But it was the footnote that caught his attention.
A whispered legend of the Necropolis—the City of the Dead—buried somewhere beneath the shifting dunes.
Rhys tapped his chin, staring at the golden expanse.
A kingdom built on sand and secrets. And a ‘City of the Dead’ that’s conveniently missing?
That sounds less like a myth and more like a hidden directory waiting to be breached.
Ah… all I’m missing is a leather fedora hat and a whip.
He shifted his focus northeast, where the map rose into jagged plateaus.
The Windfall Kingdom.
To most travelers, it was a land of breathtaking vistas. To Rhys, it was Aetheria’s aerial supremacy hub. The relentless winds weren’t a hazard—they were a power source. The kingdom had optimized its entire military around them, deploying wyverns and griffins as high-mobility biological units.
Air-traffic control with teeth.
His eyes lingered on the sketches—but awe never came. Instead, skepticism did.
Strapping yourself to a living creature with its own instincts, moods, and teeth?
Hard pass.
He preferred engines. Not biological flight units that might decide to snack on their pilot mid-air.
Still, his internal calculator spun up.
What’s their cruising speed? Their operational range?
And more importantly—how much “fuel” does it take to keep a ton of feathers airborne over open ocean?
Good luck to them.
Personally, I'll stick to solid ground. No amount of insurance covers "accidental pilot consumption.
Farther north, the Northreach Kingdom crowned Aetheria in ice.
To Rhys, it wasn’t just a kingdom—it was a massive resource extraction tier. Jagged glaciers and perpetual snow formed a landscape reminiscent of Siberia on its worst possible day. Beneath the frost lay its real value: mana crystals and rare minerals mined from deep ice caverns, rumored to tunnel all the way into the Underworld.
Rhys squinted at the lines marking those subterranean routes.
Definitely not on my list of vacation spots.
Unless I suddenly develop a fetish for igloos and frozen fish… I’ll pass.
Moving toward the central-northern region, the map softened at last into a lush mosaic of cerulean and emerald.
The Verenne Kingdom.
To a poet, it was the Land of a Thousand Streams.
To Rhys, it was the continent’s primary circulatory system—a colossal feat of hydraulic engineering.
This wasn’t merely a farming district. It was the biological lungs of Aetheria: a massive carbon sink, a life-support system quietly keeping the world breathing.
The Amazon of this world, he mused, leaning closer to the parchment.
He lingered over the map, studying how the canals intersected with the natural terrain. It was a masterpiece of fluid dynamics—elegant, efficient, and deliberate. Even by modern standards, it was impressive.
For the first time since opening the book, his dry cynicism flickered, replaced by a spark of genuine curiosity.
“A civilization built entirely on the rhythm of water,” he whispered.
“I’ve seen images of the great river basins back home… but this? I wouldn’t mind seeing this one in person.”
To the southwest sprawled the Dravenholm Kingdom—its rugged territory defined by towering mountain ranges, dense primeval jungles, and ravines so deep they swallowed sunlight.
Rhys slowed his page-turning without realizing it.
Dravenholm was renowned for its mastery over Flora Magic and Beastcraft. Its people were not merely farmers or hunters, but professional cultivators of enchanted plants and breeders of arcane beasts. From mana-infused crops to magically enhanced livestock, the kingdom supplied a vast portion of Aetheria’s raw biological resources.
His thumb traced the edge of the parchment absently as he read, eyes narrowing just a fraction.
As a result, Dravenholm stood as one of the continent’s largest exporters of magical materials—feeding not only civilian markets, but also alchemical workshops, mage academies, and military supply chains across multiple kingdoms.
“…So this is the food chain,” Rhys murmured.
Not a battlefield kingdom. Not a scholarly one either. But remove Dravenholm from the map, and half the continent would start starving—quietly, efficiently, and all at once.
Lastly, nestled like a strategic buffer between the two heavyweights—Arcadia and Calandria—sat the Crucifier Holy See.
It was little more than a sliver of land, yet its influence ignored borders entirely. Governed by a High Pontiff claiming divine revelation from Luminara, the Goddess of Light, the Holy See functioned as both spiritual anchor for the masses—and the continent’s primary arbiter of truth.
Rhys leaned back, eyes tracing the radiant icon etched into the parchment.
The ultimate middleman, he thought.
It was a structure he knew well from Earth’s history: a centralized monopoly on the divine, founded on the claim that the creator spoke through only one mouth. By placing itself between the people and their god, the Church didn’t need a massive army.
They simply owned the map to the afterlife.
He followed the faint lines marking the Holy See’s influence bleeding into foreign lands—a subtle hegemony propagated through sermons and doctrine rather than steel.
At least this world isn’t entirely alien,
Rhys mused, a dry smile tugging at his lips.
For all its fantastical flair, the game remained the same. People discovered something wondrous—and someone immediately declared themselves the only ones qualified to explain it.
A convenient way to keep everyone else in line.
He tapped the symbol of the Goddess, his thoughts drifting from ecclesiastical structure to the nature of the deity itself.
Now the real question…
he thought, glancing up at the dim ceiling of his room.
Is there actually a Luminara watching over Arath? Or is this just the oldest marketing campaign in history?
At first, he’d feared this world would be utterly incomprehensible—something torn from an alien dreamscape. But the kingdoms, their politics and cultures, felt disturbingly familiar.
He exhaled softly and closed the book.
The geography, history, and political foundations of Aetheria now lay etched in his mind—though true mastery would require far more study.
“The illustrations, the tools, the architecture…” he murmured.
“They suggest a civilization roughly equivalent to Earth’s medieval era.”
He paused.
“Perhaps magic stunted scientific development. Why build technology when magic can do the job instead?”
Rhys flipped back through the pages, returning to the two dominant powers—starting with the eastern hegemon: the Kingdom of Arcadia.
Arcadia was defined by its monopoly on arcane scholarship, a nation built upon magic that had kept it at the top of the food chain for centuries. Yet for all its claims of absolute monarchy, real authority lay in a brittle power-sharing arrangement with the Council of Mages.
A perpetual compromise between the Crown—and those who actually understood the laws of reality.
Then there was his current residence.
The Arcadia Academy of Magic.
Floating upon the tranquil waters of Lake Aetherion, the Academy functioned less as a school and more as a sovereign bubble. An ancient covenant granted it complete autonomy, shielding it from royal authority like a historical firewall.
“An intellectual tax haven with borders,” Rhys muttered as he studied its silhouette.
“They carved out a sovereign domain in the heart of a superpower.”
He snorted softly.
“This isn’t just a school. It’s a sanctuary for people the King is too afraid to govern.”
Turning the page, the book seemed heavier in his hands—the political gravity of this world pressing down on him.
Humans made up the vast majority of Arcadia’s population. On rare occasions, Light Elves or Half-Elves appeared—typically scholars, archivists, or specialists in arcane disciplines.
“Elves…” Rhys muttered.
“Don’t tell me we’re talking about the pointy-eared, millennia-old kind. Please don’t let this be that fantasy.”
A dry chuckle escaped him—then died instantly.
There, etched in fine ink, was an illustration.
Tall. Elegant. Ageless. Long ears. Eyes that had watched centuries pass.
“…Wait,” he muttered.
“Did Tolkien visit Arath?”
Despite being the continent’s most prestigious magical institution, Arcadia did not permit unchecked spellcasting. Beyond low-tier cantrips, all higher-level magic was tightly regulated by the Mage Towers.
These Towers functioned as magical law enforcement—monitoring spell usage, enforcing bans on forbidden incantations, and maintaining public order.
“In this world,” Rhys murmured,
“magic occupies the same role science does back home.”
A force of creation in the right hands.
A weapon in the wrong.
His lips pressed together as an unwelcome memory surfaced—the lab. The explosion. The blinding white flash.
Or perhaps—
He stopped himself and shook his head.
No matter the truth, he had died in that world. There was no going back.
Flipping ahead, he reached Arcadia’s ideological mirror—and only true rival.
The Calandria Empire.
Known as the Blade of the West, Calandria was a hyper-militarized absolute monarchy governed by an Imperial War Council. Where Arcadia pursued theory, Calandria pursued application.
By treating dungeons as resource mines, they had industrialized arcane research, pioneering arcanotech and factory-scale magical warfare.
Their Imperial War Academy didn’t train scholars.
It manufactured weapons—shaping children from youth into elite battle-mages and dungeon assault specialists.
The industrial–military complex of the arcane world.
The so-called armistice between the two powers was nothing more than a thin crust of ice over a boiling sea of conflict.
It wasn’t peace.
It was a Cold War fueled by a mana-based arms race.
Rhys closed the book slowly and sank onto the bed, the weight of geopolitics pressing down on him.
“It’s always the same story,” he whispered.
“Two superpowers. One finite resource. And a ticking clock.”
If even half of it was true, then this world didn’t merely respect magic.
It weaponized it.
Mages weren’t scholars or mystics—they were strategic assets. Engines of war. Elevated above common folk and woven directly into systems of power.
Nobility in all but name.
“No matter the world…”
Rhys muttered bitterly, reclining onto the bed.
“There’s no escaping politics and war.”
He closed his eyes.
Sleep came quickly.
And with it—another dream.
He stood on a battlefield drowned in chaos. Soldiers surged around him, first armed with guns and modern weaponry. Then, slowly—eerily—they began to change.
Rifles dissolved into spell sigils. Tanks collapsed into summoning circles. The uniforms changed. The language changed. The weapons changed. But the screaming didn't.
And the ruin didn't.
This glossary defines historical and geographical terms introduced in Chapter 3. It expands upon the world of Arath and its major powers
World Building
Arath
A parallel world or alternate universe in which the protagonist awakens, now inhabiting the body of a young man called Rein. Arath contains structural and physical similarities to Earth, including gravity (~9.8 m/s2), 24-hour cycles, breathable atmosphere, and familiar environmental constants—suggesting a mirror world or multiverse scenario.
Note: Rhys suspects its foundations are intentionally designed to resemble Earth for reasons unknown.
Aetheria
The central continent of Arath and the heart of political and magical power. It is surrounded by four outer
Continents:
– Galathor (north, frozen)
– Avonia (west)
– Arvandor (south)
– Elderia (east, storm-shrouded)
Kingdom of Arcadia
A dominant magical superpower in Aetheria known for its arcane research monopoly and its ideological rivalry with the Calandria Empire. While technically an absolute monarchy, Arcadia is governed in practice by a fragile power-sharing arrangement between the Crown and the Council of Mages.
Its most powerful mages act as lawmakers, enforcers, and regulators of magical conduct.
Calandria Empire
Arcadia’s ideological and military mirror. A hyper-militarized empire with an industrial approach to arcane development, it treats dungeons as “resource mines” and magic as a scalable asset. Its Imperial War Academy trains mages not as scholars, but as war assets.
The rivalry with Arcadia mirrors a Cold War fueled by a magical arms race.
Crucifier Holy See
A powerful religious dominion that operates independently of other political powers. Led by a High Pontiff who claims divine communication from the Goddess Luminara, the Church exerts continental influence by controlling religious narrative and spiritual authority.
Its power lies in persuasion and ideological control rather than military might.
The Kingdoms of Aetheria (Geopolitical Notes)
– Aramel Freeport
A diverse trade hub and Aetheria’s main port. Chaotic but rich in information flow.
– Zeppelin Desert Kingdom
Built on the Saharadus Desert. Known for relic trading and myths like the Necropolis.
– Windfall Kingdom
Masters of aerial mobility using wyverns and griffins. Strong wind-based infrastructure.
– Northreach Kingdom
Icy resource zone, known for deep mana crystal mining and rumored access to the Underworld.
– Verenne Kingdom
A lush hydrological powerhouse, functioning like the Amazon. Important for ecological and agricultural stability.
– Dravenholm Kingdom
A jungle kingdom known for Flora Magic, Beastcraft, and possible elven ancestry.
Location
Arcadia Academy of Magic
A floating academy on Lake Aetherion. Though physically in Arcadian territory, it is politically autonomous due to an ancient covenant.
It’s described as an "intellectual tax haven", akin to a sovereign enclave of elite mages who operate outside even royal oversight.
Functions as both magical university and de facto think tank.
Mage Towers
The magic-regulating institutions within Arcadia. They enforce spellcasting laws, ban forbidden magic, and monitor mages’ behavior—essentially serving as magical police and court system.
Key Characters
Rhys / Rein (update)
The protagonist now inhabiting the body of a young man named Rein. Originally a scientist from Earth, Rhys exhibits highly rational and analytical thought, and begins adapting quickly to the new world by unlocking
Rein’s memories and reflexes.
– Shows innate SI-based measurement thinking (metric system)
– Experiences linguistic and neurological integration: language, glyph recognition, and physical instincts seem "downloaded"
– Considers Rein’s body as pre-loaded with useful “software” (a metaphor for inherited skill and instinct)
Phenomenon
Language Comprehension Phenomenon
Rhys notes that though locals do not speak English, he understands everything automatically—suggesting a magical or neurological auto-translation effect. Written language, too, becomes legible over time, as if being "unlocked" rather than learned.
Books
Chronicles of Aetheria
A historical tome detailing the geography, nations, and political structures of Arath. Becomes one of Rhys’s main tools for studying the world and constructing mental maps of power dynamics.
Legend
The Necropolis
A rumored underground City of the Dead hidden beneath the Zeppelin Desert. Considered myth by some, but likely a sealed or forgotten location relevant to necromantic or forbidden magics. Rhys suspects it is more a hidden location than a myth.
Deity
Luminara
The deity worshipped by the Crucifier Holy See. Believed to be the Goddess of Light and divine truth. Religious and political powers intertwine through her doctrine.
Meta Reference
The Lord of the Rings
A high fantasy epic written by J.R.R. Tolkien, published in the 1950s. Often credited with establishing the foundational tropes of modern fantasy, including elves, dwarves, dark lords, and heroic quests. Its influence spans nearly every major fantasy franchise since.
– In Chapter 3, Rhys references it when analyzing the structure of the new world, noting that it “felt more Tolkien than Tolkien”—suggesting the setting is so archetypal that it almost feels cliché or deliberately constructed.
– His internal commentary hints that this world might’ve been intentionally designed like a high-fantasy game or novel, which raises narrative suspicion about who made it this way and why.
Tolkien, J.R.R.
(John Ronald Reuel Tolkien, 1892–1973)
British writer, linguist, and professor. Known as the father of modern high fantasy. His legendarium, including The Silmarillion, The Hobbit, and The Lord of the Rings, introduced languages, deep lore, and worldbuilding techniques that became genre staples.
– Rhys’s mental reference to Tolkien marks him as culturally literate and subtly skeptical of overly “perfect” fantasy settings—he’s genre-aware.
A leather fedora hat and whip
A humorous visual image Rhys conjures in his mind when reading about mythical ruins and lost temples in Arath. This is a pop-culture reference to Indiana Jones, the iconic archaeologist-adventurer from Steven Spielberg and George Lucas’s film series.
– The whip and fedora are signature items of Dr. Henry “Indiana” Jones Jr., who explores ruins, recovers ancient relics, and survives deadly traps—often in vaguely colonial or fantastical settings.
– The joke here implies Rhys is self-aware of the ridiculousness of such archetypes, and is lightly mocking the possibility that he’s been dropped into a “scripted” world with “scripted” dungeon tropes.
When you glimpse a world from the outside,
its order can feel familiar,
or impossibly strange—
sometimes both at once.
Onward to Chapter 4.
